A new automated cell processor offers similar collection efficiencies for key umbilical cord blood cells compared to standard methods. This closed system significantly reduces processing time, enhancing efficiency in cord blood banking.

Area of Science:

  • Hematology
  • Biotechnology
  • Medical Devices

Background:

  • Standard umbilical cord blood processing utilizes open centrifugation systems.
  • These methods result in variable recovery rates for cells and volume.
  • This variability impacts the efficacy of cord blood stem cell therapies.

Purpose of the Study:

  • To compare the efficiency of a microprocessor-controlled cell separator with closed disposables against manual separation in blood bags.
  • To analyze collection efficiencies of nucleated cells, mononuclear cells (MNCs), red blood cells (RBCs), and CD34+ cells.
  • To evaluate the processing time for both methods.

Main Methods:

  • Forty umbilical cord blood donations were randomly assigned to two processing groups.
  • Group 1: Microprocessor-controlled cell separator with closed disposables.

  • Group 2: Manual separation procedure in blood bags.

    • Main Results:

    • Automated processing showed similar collection efficiencies for nucleated cells (78.6%), MNCs (77.4%), and CD34+ cells (83.6%) compared to standard centrifugation (73.1%, 78.1%, 77.0% respectively).
    • Red blood cell (RBC) reduction was less effective with the automated system (55.5%) versus standard centrifugation (26.0%).
    • Automated processing time was significantly shorter (approx. 20 minutes) than standard centrifugation (60-80 minutes).

    Conclusions:

    • The microprocessor-controlled cell processor achieves comparable collection efficiencies for crucial stem cells.
    • The automated system offers advantages of a closed system, standardized procedure, and significantly reduced processing time.
    • While RBC reduction is less effective, the overall benefits suggest potential improvements in cord blood processing.
